HERBERT JOHN DODD, OF HERNE HILL, ENGLAND.

TOBACCO-PIPE.

To all 'whom t may concern:

Be it known that I, HERBERT JOHN Donn, a subject of the King of Great Britain and Ireland, residing at Herne Hill, in the county of Surrey, England, have invented Improvements in Tobacco-Pipes, of which the following is a specification.

This invention relates to tobacco pipes and cigar or cigarette holders having means for intercepting and removing nicotln and other condensable or liquid substance.

For such purposes it has been proposed to provide the bowl or stem of a tobacco pipe with a valve normally closed by a spring, such valve being sometimes arranged at the farther end of an extension of the stem beyond the bowl constituting a collecting chamber for material afterward expelled by opening the valve and blowing down the mouthpiece.

Now according to the present invention a tobacco pipe having means of the kind referred to or a cigar or cigarette holder or the like is provided with a device whereby the communication between the bowl or equivalent and the stem is closed by the act of opening the discharge valve and vice versa thus preventing disturbance of the contents, if any, of the bowl of the pipe while blowing out collected material and facilitating the discharge of the latter by utilizing the whole of the blowing force for its removal which is very desirable since the substance is often glutinous and not easily satisfactorily dislodged.

Figure l of the accompanying drawingr illustrates partly in central section and partly in elevation one construction of tobacco pipe according to the invention. Fig. 2 is a similar view to Fig. l illustrating another construction of pipe according to the invention.

Referring to Fig. l it will be seen there is provided below the bowl proper a of a toacco pipe a chamber ZJ that receives the stem c of the pipe, and communicates with the bowl a through passages (l. A passage c serves for the discharge of the material collected in the chamber, the said passage being normally closed by a disk valve f having a hollow spindle g which passes through and projects beyond an orifice l1, in the base of the chamber. ,Y

The spindle g houses one part of a spring y' whose other end bears against the upper wall of the chamber, conveniently against a Specication of Letters Patent. "-iiiiatioaaieaiuar'chia, 1917.v seria1No.154,2os.

centering point. The spring acts to normally close the discharge passage e by the valve f but upon pressing the spindle against the action of the spring to the limit of its movement the valve opens the said passage and closes the passage CZ so that collected material can be readily discharged by blowing through the pipe stem.

In the example the bowl proper L of the pipe is shown as formed separate from and attached to the wall of the chamber by screwing although it might be otherwise connected or the upper part of the chamber might be formed in one therewith and a separate base piece attached thereto if desired. To minimize liability of material collected in the chamber entering the users mouth, the stem, as shown at 7s, can be caused to project beyond the chamber wall.

The pipe shown in Fig. 2 differs from that shown in Fig. l in that around the orilice it for the valve spindle g a boss m extends upwardly from the bottom of the chamber b above the bowl of the discharge passage e and thereby obviates the possibility of nicotin passing around the valve stem through the orifice h. The valve in this construction is made with a depending marginal rim that surrounds the boss m` and closes the passage e.

The pipes illustrated are by ways of eX- ample for as will be understood the details might be variously modified without departing from the invention. Thus it is not essential that the spring be partly housed in a hollow spindle nor that the discharge outlet of the chamber be in the base thereof.

The invention is further applicable to suitably formed cigar and cigarette holders as well as to tobacco pipes.

lVhat I claim is A tobacco pipe having a nicotin chamber interposed betwen the tobacco bowl and the pipe stem, ythe said bowl communicating with said chamber through holes located near a central unperforated part of the bowl bottom and the bottom of said nicotin chamber being formed with a central guide hole and with a nicotin discharge hole adjacent thereto, a valve in said nicotin chamber having a depending hollow stem closed at its lower end working through the guide hole of said nicotin chamber bottom, said valve being adapted, when in its lowest position to close the nicotin discharge opening and when in its highest position being adapted to close communication between the pipe bowl Signed at Londbn",`England'thisV 23rd day and said nicotin chamber7 and a spring arof February 1917.
